Introduction
2.1 The eQ-3 group
In over 35 years, the ELV-/eQ-3 group has developed
from a technology pioneer to one of the European market
leaders in smart home.
eQ-3 stands for innovation across a broad spectrum of
technologies which, when combined with one another,
represent a major leap in customer-oriented solutions.
In the smart home area, there are numerous examples in
wireless technology and mechatronics - amongst others
in electronic radiator thermostats. The eQ-3 Group has
core expertise in battery operation, as well as in communication between two or more battery-operated devices.
With its smart home products, eQ-3 is a market leader and, by integrating IPv6 into mass-market
home automation products, the company is already turning the oft-quoted vision of the Internet
of Things (IoT) into a reality. With more than 1,000 employees, the ELV/eQ-3 Group is one of
the largest and fastest-growing employers in Germany’s East Frisia region.
Development
eQ-3 realises market requirements particularly fast, using state-of-the-art technology and best
practices while maintaining close contact with the market and customers. With more than 80
employees, the R&D team is one of the biggest and most experienced in the field of smart home
in Europe, so even very demanding projects are in safe hands.
Production and tool making
By carrying out our development work in Germany and manufacturing in the Group’s whollyowned plant in Zhuhai, southern China, eQ-3 provides the ideal combination of high-quality
German engineering and low manufacturing costs. With an extensive vertical range of

Wireless Home Control
3 WIRELESS HOME CONTROL
3.1 What is a smart home?
A smart home oers automation of recurring day-to-day operations and tasks in houses or
flats: While using an appropriate system, dierent (technical) devices and functionalities can be
connected throughout one household, oering most comfortable control and automation of
recurring tasks.
An intelligent home control system makes your house a smart home – literally an “intelligent
house”. It increases the security level in your living environment, helps to save energy and
increases the personal living comfort. A climate control solution for heating control reduces your
heating costs by up to 30 percent without any loss of comfort, whilst oering considerable cost
savings immediately. With comfortable light control, a cosy atmosphere is created at the push
of a button. Alarm systems, automated shutter control, connected door and window contacts,
smoke alarms and motion sensors protect your home as well.
To enable control also while being out of the house, modern home automation systems are
connected to the Internet. With an active Internet connection, it is possible to access the system,
control devices or request information about devices or states from a PC or with a smartphone
app at any time and almost every place.
On the one hand, a main requirement to a home control system is the security counteracting
unauthorised access from the outside. On the other hand, the used technology has to operate
reliably. Finally, the system must oer intuitive and user-friendly installation and operation. Also,
easy expansion options are an important factor. With Homematic IP, the new and optimised
smart home product range, eQ-3 has developed a system that fulfils all these requirements.

Wireless Home Control
3.2 Comparison of smart home technologies
For the transmission of data in the smart home area, i.e. communication between single components within buildings, the following technologies are primarily used nowadays:
• radio communication,
• wired BUS systems and
• Powerline adapters (via current distribution in the house).
Every system has its specific advantages and disadvantages. Which system to choose depends,
for example, on the intended purpose of either installing the smart home system in a new
building or, alternatively, of retrofitting a home. Furthermore, there are various parameters in
relation to the system that should be considered before reaching a decision.
The following provides information about the three most important system technologies and
shows their advantages and disadvantages.
3.2.1 Radio transmission
Radio-based systems use wireless radio connections for controlling and communicating
between the integrated devices.
Pros:
• Flexibility:
One of the main advantages of a radio-based system is the almost unlimited flexibility.
As no cables have to be laid, these systems can also be retrofitted without great eort
and, if required, can be easily removed. If the living situation changes, the existing
system can be easily adjusted. In addition, wireless systems are ideal if planning to
combine many dierent components with each other. At the same time, multiple
actions can be triggered and entire scenarios are realised at the push of a button. For
example, upon returning home by car and pushing a button on the key-ring remote
control, the garage door opens, the light intensity of the garden lights is increased
and the way to the entrance is illuminated. While approaching the house, the radiator
thermostat in the living room is already adjusted to the individual comfort temperature.
• Security:
There are great dierences between the radio systems in terms of security aspects.
Due to encrypted authorization control of radio commands (authentication),
unauthorised interference from the outside is almost impossible with Homematic and
Homematic IP.
• Low energy consumption:
Wireless devices are characterized by low stand-by consumption.
• Easy to install:
You can easily install battery-operated wireless devices by yourself.
10
Wireless Home Control
Cons:
• Interferences caused by other systems:
Depending on the radio frequency used, the communication between the wireless
devices can be interfered by other radio systems. This becomes particularly dicult, if
the radio system works on the same frequency like WLAN routers, Bluetooth devices
or video and audio streaming systems. Homematic IP works on a frequency band that
is insensitive to influences by these systems.
• Wireless range:
The wireless range of devices is limited. But, however, it is sucient for most situations in private households. If the wireless range may once be insucient, it can be
extended using wireless routers with Homematic IP.
• Changing batteries:
Depending on the device and operational frequency, the batteries of battery operated
devices need to be replaced in dierent time intervals (1-5 years). In many case,
battery operation is less expensive than stand-by operation of e.g. Powerline adapters.
3.2.2 Wired BUS technology
For so-called ‘wired systems’, wired BUS components are used. These devices communicate in
a BUS system via cable or plug connector. They are usually installed via DIN rail into electrical
distribution boards or as flush-mounted devices into switch boxes or junction boxes, especially
in new or commercial buildings.
Pros:
• Reliability:
Wired devices are more or less insensitive to interferences. Furthermore, the devices
are very reliable and oer low-maintenance operation as power is supplied by a
power supply unit in the installation.
Cons:
• Extension of the system:
As the communication between wired components is performed via cable connections, the extension of existing systems is more complex. For example, cables have to
be run to the distribution boar
• Installation:
Another disadvantage that arises from the installation site. Mounting and troubleshooting can only be performed by an electrician.
• Limited product portfolio:
The product range is limited to mains-operated devices. This is why the application
fields are mainly limited to network solutions within buildings. Controlling of other
functional areas such as conventional radiators using radiator thermostats is not
possible in this way.

3.2.3 Powerline
Powerline uses the existing infrastructure available in every household: the domestic power
supply system. Furthermore, there are systems using coaxial cables that have already been
installed (antenna cable for radio or television reception) for the transmission of data. Powerline
solutions are ideal if laying cables is too complex or a wireless solution can hardly be installed
due to dicult constructional prerequisites.
Pros:
• High data rate:
One advantage is that Powerline adapters oer a high data rate which is ideal for LAN
applications such as video streaming.
• Range:
The range which is the maximum line length between the adapters, is up to 300
meters for new devices.
Cons:
• Installation:
When using adapters without integrated sockets, the sockets in the house are
occupied by Powerline devices.
• Limited product portfolio:
The product range is limited to mains-operated devices. This is why the application
fields are mainly limited to network solutions within buildings. Controlling other
functional areas such as conventional radiators using radiator thermostats is not
possible in this way.
• Sources of interference:
Furthermore, devices that are connected to the power supply system can reduce the
signal range and cause interference with the communication. This especially applies
to devices with electrical motors like vacuum cleaners. Powerline networks also react
sensitively to dimmers or ballasts.

3.3 Wireless range
eQ-3 benefits from more than 30 years of experience in the field of wireless technology for
smart home applications. Homematic IP is based on the same particularly eective and robust
wireless technology like Homematic and has proven its market success with millions of devices.
The wireless range of Homematic IP exceeds the standard requirements of a typical installation.
Depending on the device type, a wireless range between 150 and 400 meters in the open air can
be reached. Experience shows that in less than 1 % of installations repeaters are used to extend
the wireless range.
Radio waves behave in a similar way as sound waves. They can pass through walls and spread
out in all directions. Similar to the volume of sound, the energy of radio waves decreases with
distance. Thus, the range of radio waves is limited.
In practice, there are factors that can influence the radio signal in a positive and negative way,
compared to the range in the open air. There are two main reasons for the reduction of radio
signals: damping and interferences.
For further information on the extension of the radio range using the Homematic IP
Pluggable Switch (HmIP-PS) or the Homematic IP Pluggable Switch and Meter (HmIPPSM), please refer to section “Range extension” on page 37.
3.3.1 Damping
Damping is defined by the installation conditions on site (e.g. a wall) and can hardly be influenced
Thus, under certain circumstances, the building materials can reduce the strength of radio signals
in such way that they reach the receiver damped, incorrectly or not at all.
For the installation position of wireless devices it should be taken into account that dampening
values are above average when it comes to materials containing metals. This does not relate to
building materials such as insulating materials with metal foils, but does relate to metal doors or
large electrical appliances such as washing machines, for example. Metal bodies can have both
dampening as well as amplifying eects to the radio signal.
Particularly in rental flats, it is often dicult to find out about the walls’ construction. Therefore,
it is recommended to install the transmitter and receiver only temporarily for testing the quality
of the signal transmission.
With an open air range of 150 to 400 meters, Homematic IP
buildings without any transmission errors.
can usually be used in private
.

The following table gives an overview of the damping eects of single building materials:
Building material Damping
Pumice stone/autoclaved aerated concrete
Gypsum and gypsum plasterboard
Uncoated glass
Metallised glass
Wood
Metal grille (e.g. in plaster)
Press boards
Stone slabs
Brick
3.3.2 Interferences
Interferences are caused by electrical devices in households and negatively influence the signal
quality of radio components. These interferences are substantially reduced by keeping a distance
as large as possible between the radio components and those potential sources of interference.
This applies in particular to objects that emit radio waves:
• computers
• radio speakers and radio headsets
• audio and video systems
• alarm systems
• mobile phones and cordless phones
• microwave ovens
• electronic ballasts for fluorescent lamps
• audio baby-monitors
Dierent radio systems that are used for smart home applications communicate on the 2.4 GHz
frequency band. Examples are systems that are based on Bluetooth Smart, WLAN and Zigbee.
Homematic IP is not influenced by interference from such systems, as it works in another
frequency band than e.g. Bluetooth, WiFi, video and audio streaming systems or DECT phones.
3.3.3 Reflections and interference from radio waves
Radio waves are redirected (reflected) on all surfaces. This oers the advantage that signals reach
the receiver even if it is located in the radio shadow. Radio shadows occur if radio components
are not available directly, in a straight line, e.g. because metal objects dampen the radio signal. A
temporary test setup should be used to make sure that the reflection is sucient under certain
circumstances.
Interference is a phenomenon within a radio system installed in the house. It occurs, if the
antenna receives both direct as well as reflected waves or radio wave of other transmitters. Due
15
Wireless Home Control
to this interference eect, there may be a damping or overlapping of the radio signals. In many
cases it can help to slightly change the position of the components.
3.4 Information about radio compatibility
With Homematic IP as a radio-based system, it is helpful to address the question if health risks
might occur due to radio wave impact.
There are no confirmed statements about health eects caused by radio systems for home
automation. With such low transmission power, it is not possible to measure direct eects.
Results of a long-term study are not yet available. Therefore, it makes sense to compare it with
widespread radio techniques as used for WiFi and mobile networks as well as for cordless DECT
telephones.
During the evaluation of the biological compatibility, a series of dierent factors like the transmission power, the transmission duration and in particular the distance of the body to the radio
devices play a role. All these factors influence the level of radiated energy that actually reaches
the body in typical usage situations (exposure level) into the body. Radio systems should in any
case comply with all legal requirements related to security and environment.
Transmission power and duration
In direct comparison, Homematic IP devices work with much lower transmission power.
According to statements from the Federal Network Agency, a transmission capacity of up to
100 mW for WiFi devices is allowed, while devices in mobile networks may reach a maximum
power of more than one watt
1
.
On the other hand, Homematic IP devices usually operate with a transmission power of 10 mW.
This already proves a typical dierence by a factor of 20 in the transmission power and thus
regarding the potential exposure.
The transmission duration of radio telegrams for the communication between Homematic
IP devices takes place in a range of milliseconds and is usually between 10 to 30 milliseconds. Most of the time, the devices are in “sleep mode” and are only active if a status
message
is transmitted. If, for example, the room temperature is set via the wall thermostat,
it ‘wakes up’ the connected radiator thermostats and transmits the new setpoint temperature. Compared to WiFi, mobile and DECT networks, where almost permanent radio
activity is given, the transmission o
f Homematic
IP is very infrequent. Furthermore, a
maximum transmission time of 36 seconds per hour and device defined by law is set for the
frequency band used for Homematic IP. In a normal installation, this is not reached at all.
Regarding the transmission power and duration, the following comparison can be made: A
typical conversation via mobile phone takes approximately 5 minutes with a permanent transmission power of at least 300 mW. In comparison, a HomematicIP actuator transmits approximately 1 second per day at 10 mW power in total.
In other words: In order to reach the radio pollution of a five-minute conversation via mobile
phone, one Homematic IP actuator would have to be switched on daily for more than 25 years.

Wireless Home Control
Furthermore, the actuator would have to be situated in the immediate vicinity of the body (like
a mobile phone at the ear).
Legal requirements
All Homematic IP devices are, in addition, marked with the CE sign, indicating that the product
has been tested and comply with the legal requirements of the EU guaranteeing health
protection, security and environmental protection before they are placed on the market.
The eQ-3 group has received a statement from the internationally renowned test laboratory
Phoenix Testlab, proving the compliance of Homematic IP devices
EN 62479. In detail, the regulation implies the “compliance of low power electronic and electrical
equipment with the basic restrictions related to human exposure to electromagnetic fields (10
MHz to 300 GHz)”
2
. According to this declaration, the Homematic IP radio modules are far below
the “radiation” limits defined by law.
It can, however, be assumed, that no health risks are caused by the radio technology used within
the Homematic IP system
. This also applies to persons with hearing aids and cardiac pacemakers
– another aspect that has been proved during tests of our own department for electromagnetic
compatibility (EMV).

Overview of HomematicIP
4 OVERVIEW OF HOMEMATICIP
Homematic IP is the next generation of the successful smart home system Homematic by eQ-3.
The constantly growing product range of Homematic IP includes devices for climate control,
security, weather, light and shutter control applications as well as various accessory components. The climate control devices oer demand-based room-by-room control of radiators
throughout the entire house, enabling users to save up to 30 % on their energy costs. In addition,
floor heating systems can eciently be controlled with Homematic IP products. No movement
goes unnoticed with the security components. Users are informed whenever windows and
doors are opened. One look at the app is enough to find out that everything is all right at home.
Comfort is enhanced with switching and dimming actuators for light control as well as products
for automation of shutters and blinds. All Homematic IP devices for brand switches can be
easily integrated into the design of existing switch series using our adapters. The Homematic IP
Weather Sensors do not only oer the possibility of recording and evaluating measured data.
Furthermore, in combination with products of other areas, it is for example possible to adjust the
smart home to current weather conditions, e.g. by moving up the shutters in case of strong wind.
For operation, the Homematic IP Access Point in connection with the HomematicIP app (no
recurring costs), the Homematic Central Control Unit CCU2/CCU3 or an appropriate partner
solution is required. Once installed, the system can be controlled comfortably via app, remote
control or wall-mounted push-button. In addition, the combination of almost all devices and
conditions of various application areas is possible. Therefore, the Homematic IP app oers
pre-programmed functionalities as well as the configuration of individual automation rules. There
are virtually no limits to the users’ creative leeway. Another benefit is oered by controlling the
system using voice control services like Amazon Alexa and Google.
Single devices are configured by the Homematic IP cloud service, which is run exclusively on
servers located in Germany and therefore complies with European and German data protection
guidelines. All data stored in the Homematic IP cloud is completely anonymous. However, it
does not allow any conclusion about the user’s identity and the individual usage behaviour.
Furthermore, all communication between the Access Point, cloud and app is encrypted. As
neither during nor after installation of the app you will need to provide private data such as name,
email address or mobile phone number, your anonymity is protected 100%.
Homematic IP builds on the strengths of Homematic, implements IPv6 – the next generation
Internet protocol – in each device and therefore oers a solution tailored to the Internet of
Things (IoT). Thanks to the open platform, the solution can be flexibly expanded at any time
- Via the Homematic Central Control Unit CCU2/CCU3 all Homematic IP devices can also be
integrated into an existing Homematic system.
As the devices communicate via radio, they can be retrofitted into houses really easily. All
products communicate via the robust and reliable 868 MHz Homematic IP wireless protocol.
This means that there is no interference whatsoever from WLAN, Bluetooth or other radio
standards operating within the 2.4 GHz frequency band.
18
Overview of HomematicIP
4.1 Application areas
4.1.1 Heating and climate control
Homematic IP oers demand-based control of radiators room-by-room in the entire house,
enabling increased living comfort and energy savings of up to 30 %. The Homematic IP Window
/ Door Contact detects open windows and doors and automatically turns down the heating
during ventilation. In addition, ecient floor heating control that oers operation via app can be
realised with Homematic IP. The system detects the required heat for single rooms and - unlike
conventional heating circuit control systems - intelligently circulates the hot water into multiple
heating zones. This provides load balancing and efficient energy distribution thanks to the
continuous flow of heating water. The room temperature is regulated via radiator thermostats,
an installed wall thermostat or simply via app. Also, individual heating profiles can be created
with Homematic IP. Afterwards, your heating is controlled automatically and makes the everyday
life easier. However, you can still react flexibly to changed conditions and adjust the desired
temperature according to your needs.
4.1.2 Security and alarms
No movement goes unnoticed with Homematic IP security components. Our security and alarm
products increase the protection against break-ins and the sense of security inside the own four
walls.
In alarm mode, users are informed whenever windows and doors are opened. Motion detectors
oer reliable monitoring for inside and outside areas while sirens and smoke alarms trigger an
alarm in case of break-ins or fire.
Just a quick glance at the app is all it takes to see that everything is as it should be at home. Even
from afar, there is always a way to find out if doors or windows have been left open.
The alarm mode can be easily activated via app or Homematic IP Key Ring Remote Control. For
example, if the presence mode is activated, the system triggers an alarm as soon as windows
or doors are opened unauthorised. During activated “absence mode”, also sensors for indoor
areas like the motion detector are included. In case of alarm, an audio signal can be triggered
via the Homematic IP Siren or the Smoke Alarm and a push notification is send to all connected
smartphones. The alarm protocol provides an overview of all activities in your home at any time.
4.1.3 Light and shade
Comfortable switching and dimming of lights creates a sense of well-being at your home. Thus,
a comfortable atmosphere for TV evenings is created via the app as the ceiling light are dimmed
to a desired brightness level while the floor lamp is switched on. Also, the sense of security is
increased with an illuminated driveway or house façade in the evening. Homematic IP products
for light control are easily integrated into the installations of a home since existing frames and
rockers can continue to be used.
19
Overview of HomematicIP
Shutters and blinds darken rooms, create a sense of privacy and increase security. With shutter
and blind actuators, the window coverings are set up in just a few single steps using the
Homematic IP app. Afterwards, they can be raised or lowered automatically.
Actuators are controlled comfortably via individual week profiles, and can also be connected to
the sunrise and sunset. Furthermore, active shutters and blinds make the house look inhabited
even if not at home, thus actively increasing the security. Another advantage: In case of increased
room temperatures due to strong sunlight, shutters or blinds are automatically lowered to
prevent the room from heating up.
The Homematic IP Blind Actuators also allow exact adjustment of the slats position of exterior
and interior blinds. If required, also the integration of awnings into the smart home is possible
with Homematic IP. The automatic storm protection avoids damages to shutters, interior blinds
and awnings during unfavourable weather conditions and thus raises or lowers the window
coverings.
4.1.4 Weather & the environment
With the weather sensors, the Homematic IP smart home system is automatically adjusted
to current weather conditions. In connection with other Homematic IP devices, the sensors
automatically trigger commands for moving awnings, interior blinds or shutters up and down in
case of certain weather conditions, providing active protection of the house. Users have almost
unlimited possibilities for creating individual rules. For example, in case of strong sunlight and
inactive security mode, the awning is automatically extended to 80 % or with a previously defined
rainfall volume, the drainage pump is activated for a certain period of time.

4.2 Why Homematic IP is the first choice: Your benefits
Simplicity
The entire solution can be intuitively set up and comfortably controlled via smartphone app.
Single devices are configured by the Homematic IP cloud service. As the devices communicate
via radio, they are retrofitted into houses.
Interference immunity
Homematic IP is based on the 868 MHz radio band. There is no interference whatsoever from
WLAN, Bluetooth, video streaming or other users of 2.4 GHz.
Superior range
Reliable communication between Homematic IP devices works even over a distance of a few
100 meters. Even for remote places there is no need to worry about the functionality of the
chosen smart home solution.
Uncompromising security
During installation of the system, the communication of Homematic IP is secure and cannot be
manipulated. During operation, all radio packages are encrypted and authenticated. Reading,
changing or repeating data or other kind of attacks are impossible. Similar to online banking, the
established AES-128 and CCM standards are used.
Battery operation
Homematic IP focusses on battery operated devices in order to enable smart home installations
also in existing buildings. The products can be easily screwed on to radiators or stuck to walls.
Thanks to the low energy consumption of the devices, batteries usually only need to be replaced
every two years, or even less frequently.
Reliability
All Homematic IP products oer permanent bidirectional communication. Every radio command
is confirmed by the addressed device. The current status of all devices can be clearly shown.
Privacy policy
For setting up the system, no personal data has to be provided. The Homematic IP cloud is only
operated on servers located in Germany. The operation does therefore comply with European
and German privacy policies.

Overview of HomematicIP
4.3 Functionality of HomematicIP
The Homematic IP system basically consists of the following components:
• Homematic IP Access Point
• Homematic IP cloud
• free Homematic IP smartphone app
• single wireless components of the corresponding Homematic IP solution.
In connection with a router, the Homematic IP Access Point is the interface that connects your
wireless Homematic IP components with the Internet.
The Homematic IP cloud takes over communication between the free smartphone app and the
Homematic IP Access Point as well as saving and managing data, e.g. information about which
devices have been connected, which devices belong to a group in a room or details about their
configuration.
All data stored in the Homematic IP cloud is completely anonymous. However, it does
not allow any conclusion about the user’s identity and the individual usage behaviour.
Identifying a Homematic IP user is only possible as part of a criminal prosecution or
based on a court order.
The Homematic IP smartphone app, together with the cloud and the Access Point, enable the
setup, programming and controlling of your smart home system. Scanning via the app makes
integration of single Homematic IP components very easy by simply scanning the device QR
code. To make sure that the system continues to run also in case of Internet failure, all necessary
connections between the devices are determined by the Homematic IP cloud service and
created automatically. Thanks to direct connections between the devices it is ensured that
operation still continues also during an Internet failure.
All communication between the Access Point, cloud and app is encrypted. Neither during
nor after installation of the app, you will need to provide private data such as name, email
address or mobile phone number. Your anonymity is protected 100%.
All Homematic IP devices can be integrated into existing Homematic systems via the Homematic
Central Control Unit CCU2/CCU3. In this case it is possible to configure and operate the devices
via a web interface on a PC. When using a CCU2/CCU3, the data is stored locally in the Central
Control Unit and not in the cloud.

The main aspects have been ergonomics and usability. This also applies to each single device:
the design and functional elements have been reduced to the essentials, which significantly
simplifies the operation.
Detailed information about the single Homematic IP devices can be found in the datasheets of the Homematic IP devices, available for download at www.eQ-3.com.
4.4.1 Homematic IP cloud
The Homematic IP cloud enables communication between the app and the Access Point as well
as saving and managing of system relevant data. This implies e.g. information, which devices
have been taught-in or connected, as well as details about the configuration.
All communication between the Access Point, cloud and app is encrypted. No private data is
necessary when using the smartphone app and the Homematic IP cloud. The system is easily
put into operation by scanning a QR code and pressing the system button of the Access Point,
making installation secure and anonymous.
4.4.2 Homematic IP smartphone app
Via the Homematic IP smartphone app you can easily set-up your smart home solution. The app
oers step-by-step guidance through the entire installation process. All necessary links between
the devices are established automatically.
After set-up, the app takes over the function of a central control unit, enabling you to control
and configure your entire Homematic IP system. In addition, the app informs you about the
status of your devices at all times.
No matter the location:
With the free smartphone app, everything is in sight whenever needed.
Control your smart home at any time
from any place.
Simply comfortable.
24
Overview of HomematicIP
4.5 General system and flashing behaviour
Almost all Homematic IP devices are equipped with a system button with the Homematic IP
symbol
In its function as system button, it is used for reset as well as for manual teaching-in of
Homematic IP devices.
In its function as device LED it works as status display as well as indication of system states using
dierent flashing sequences, e.g. for successful transmission of a new setpoint temperature.
.
This enables execution of system functions, for example restoring of factory
settings (reset) or restart of the teach-in procedure (connection of devices).
For single-channel actuators like the Homematic IP Pluggable Switch it is
also possible to change switching status (on/o) of the device via the system
button.
Teaching-in (connection of devices):
After inserting the batteries or switching on the power supply, the teach-in mode of the
Homematic IP devices is started automatically. The device LED flashes orange every 10 seconds
- as long as the teach-in partner has been found or the teach-in time of 3 minutes has passed.
The teach-in mode can be started again by pressing the system button one time shortly.
Normal operation:
In normal operation, command transmission (e.g. at the wall-mount remote control) is displayed
by an orange flashing signal. If the command has been successfully executed by the receiver,
it will be displayed by the device LED shortly flashing green. If the transmission failed, it will be
displayed by the device LED shortly flashing red.
Battery status:
If the battery load of a Homematic IP device is low, it will be indicated in advance. In this case,
the device LED shortly lights up orange once after successful or failed transmission of a radio
command.
You will find an overview about all flashing signals of Homematic IP devices in the appendix
“Overview flashing behaviour of Homematic IP devices” on page 202. Furthermore, each device
has a device-specific flashing behaviour. This especially applies for the Access Point. For further
information, please refer to the manual of the corresponding device.
